这个问题困扰我一天了，mongodb已经连接了就是不行插入不进去数据，一执行插入的时候就会报连接超时
MongoClient mClient = new MongoClient("dds-2ze4c67d85f827b41.mongodb.rds.aliyuncs.com",3717);
MongoDatabase db = mClient.getDatabase("root");  //数据库用户名
System.out.println(db.getName());
System.out.println("1");

//得到集合，这里取"text"
MongoCollection<Document> doc = db.getCollection("test"); //相当于表一个集合
System.out.println(doc.getDocumentClass());
System.out.println("2");
//插入一个document
doc.insertOne(new Document("name","张三"));  //执行到这里就失败

System.out.println("3");
